Summary: Defective specular lighting support makes certain games
                    hardly playable
           Product: Wine
           Version: 0.9.53.
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]

In this case Blade of darkness, suffer heavy performane issues when a specular
lighting is draw on the screen, dropping framerate to 1fps or below on Direct3D
modes, even at lower resolution modes like 640x480.

I can confirm that is a specular lighting issue, because one of the fixed D3D
plugins that brings the game is for 3Dfx Voodoo 1 and 2 cards that didn't had
hardware support for specular lighting, and with these game runs flawless, in
the other side the rest of the D3D plugins runs at full framerate except when a
specular lighting is drawn in the screen, like when you're looking at a torch,
then is when framerate fall to its minimun.

Also older wine versions complaints about specular lighting drawing, latest one
(0.9.53) suffer exactly the same problem of any other wine version I have
tested with this game.

I add some wine logs
